2012年手机将实现无线充电

    日本富士通实验室的研究人员开发了一种无线充电系统，可同时给一定范围内的手机、数码相机及手提电脑等各种移动设备充电，无需使用电缆。该系统最早可于2012年正式推出使用。该系统被认为是世界上首个无线充电系统，其工作原理是利用充电器和电子设备之间的磁场来传输电能，实现无线充电的范围最远能达到数米，该技术发展成熟后甚至可用于电力汽车的充电。研发人员表示将把无线充电系统置入电子产品中，这样用户以后充电时就不用考虑充电器的型号了。此类产品最早将于2012年面世，但他们没有透露产品的预计售价。
    Mobile phone users will be able to charge their devices wirelessly² for the first time from 2012.
    Fujitsu, the Japanese technology company, has created a system capable of simultaneously³ charging multiple portable electronic devices such as mobile phones, digital cameras and laptop computers without the need for cable connections.
    Electric cars users may also eventually be able to charge their vehicles wirelessly using the same technology according to Fujitsu, which unveiled a prototype system at an Institute of Electronics, Information and Communication Engineers conference at Osaka Prefecture University.
    Claiming to be the world's first of its kind, the technology works on the basis of the transmission of electricity using magnetic fields between the charger and the electronic device.
    The system enables wireless¹ charging at distances of up to several metres, with the ultimate aim of installing public "charging spots" on the streets in order to enable easy charging around the clock.
    Scientists at Fujitsu Laboratories are planning to commercially sell products incorporating the new wireless charging system as early as 2012 but did not disclose how much they would cost.
    "This technology paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions⁴ on their position with respect to the charger," the company said in a statement.
    The soaring popularity of portable electronic devices ranging from iPads to e-readers is expected to fuel a boom in wireless recharging technology developments over the coming decade.
    Mobile phone users in Japan can currently top up their batteries using disposable portable plug-in battery-operated devices – available at most train stations and convenience stores – although phone companies warn prolonged use can damage the phones.
    The new system unveiled by Fujitsu, however, is significantly more sophisticated and represents the next generation of portable recharging systems using highly tuned⁵ wireless technology. The company added: "We are also looking at applying the results of this work to fields other than portable electronics, including power transmission between circuit boards or computer chips, and providing mobile charging systems for electric cars."
